    I absolutely love the phone I purchased through backmarket. I purchased the premium grade phone and it is totally flawless. I thought the battery life would have been premium and that's the only negative. the phone itself works perfect and doesn't have a single flaw. I paid a great price and helped mother earth by buying refurbished. Every device I purchase in the future will be through backmarket.

    The transaction was perfect. Device works great. My only gripe is my device came with a few pretty deep scratches, which drive me nuts. They applied a glass screen protector, but I can still see them underneath. The device works perfectly and is otherwise in great shape.

    First purchase from Back market and it was a great experience. I chose a seller with great reviews and the phone I received was just like new! The whole process from start to finish exceeded my expectations, and I will purchase again.

Reborn vs. brand new

Here’s what you help prevent on average by choosing a reborn smartphone over a brand new one.

That's like driving an SUV from NYC to Chicago.

That’s around the weight of a baseball.
